檢視Nordic, nRF52 Preview DK的原始碼

The '''nRF52 Preview DK''' is Nordic's development kit for the nRF52832. These notes cover the SDK, JLink, the GCC toolchain, and programming the board.

== Prepare ==
=== Install SDK ===
# Get latest SDK from https://developer.nordicsemi.com/nRF52_SDK/nRF52_SDK_v0.x.x/ (ex. nRF52_SDK_0.9.2_dbc28c9.zip)
# Get SDK with FreeRTOS example from http://developer.nordicsemi.com/nRF5_SDK/nRF5_SDK_v11.x.x/ (nRF5_SDK_11.0.0-2.alpha_bc3f6a0.zip)
# Edit ./components/toolchain/gcc/Makefile.posix to fit your toolchain setting if necessary

=== Install JLink ===
# Download "Software and Document pack" from https://www.segger.com/jlink-software.html according your platform (ex. x86_64)
# decompress and make a symbolic to /opt/SEGGER/JLink
## ln -s ~/Downloads/JLink_Linux_V510c_x86_64 /opt/SEGGER/JLink
=== Toolchain ===
sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo apt-get update
sudo apt-get install gcc-arm-none-eabi
=== Programming ===
<syntaxhighlight lang="bash">
1. Softdevice
    ex.
    sudo /home/tommy/projects/mbed/nRF52/NrfJProg_7_7_0_Linux/nrfjprog --family NRF52 --program ~/projects/mbed/nRF52/s132_nrf52_1.0.0-3.alpha/s132_nrf52_1.0.0-3.alpha_softdevice.hex

2. change dir to example 
    ex.
    sudo ~/projects/mbed/nRF52/NrfJProg_7_7_0_Linux/nrfjprog --sectorerase --family nRF52 --program _build/nrf52832_xxaa_s132.hex

3. sudo ~/projects/mbed/nRF52/NrfJProg_7_7_0_Linux/nrfjprog --sectorerase --family nRF52 --program _build/nrf52832_xxaa.hex
4. power recycle to take effect
